Abstract
An improved surgical suture remover is formed of a single elongated strip of resiliently flexible material having a bend substantially midway in its elongation to define first and second shanks respectively carrying a blade and a shearing portion at their corresponding ends. The blade includes a cutting section, and the shearing portion includes a cutting edge, and the blade and shearing portion are pivotally connected for movement of the cutting section and cutting edge toward and away from each other along a cutting plane to cooperatively sever a suture therebetween. An elongated suture gripping element unitarily depending from the shearing portion includes a contact area for suture gripping contact with the cutting section during an operating stroke or jaw closure of the instrument. In another embodiment there is a cutting blade and a shear blade forming a scissors, with each blade having an elongated raised rib, and an abutment shoulder. The ribs render the blade tips inflexible and bow the blades relative to each other, in order to provide edge-to-edge contact between the blades.
